Honestly? There’s not a companion I don’t see Bill getting along well with.

She and Rose would be good, supportive friends, swapping stories about their families and lives and probably hanging out together in their pjs eating ice cream.

Bill would really respect Martha, and Martha would be only too happy to explain the science of things to Bill. They would geek out about scifi and Harry Potter together. When the reality of all the deaths she’s witnessed got too much for Bill, she could depend on Martha to listen and understand, since she too knows the cost of traveling with the Doctor.

Donna would immediately adopt Bill as her younger sister and the two of them would make the Doctor’s life hell, being constantly sarcastic to him and to each other.

Once Jack realized that Bill was gay, they would probably do the thing where they flirt in a ridiculously over-the-top, not at all serious way all the time. They would laugh a lot together and make jokes about straight people.

Amy’s never really had a girl friend before, so Bill could be Amy’s first real introduction to sleepovers and going to the pub with friends and all those normal things that Amy is so separated from, and in return, Amy would tell Bill all the stories that she has in her head, the ones she remembers as well as the ones she’s making up.

Bill and Rory both have the ability to see situations clearly and not get overwhelmed by the glamour of it, so they would probably really appreciate having someone else who’s straightforward and who just gets it.

Bill and Clara would definitely have not-so-subtle crushes on each other. Their dynamic would be all about flirty banter while saving the world.

I think River would tend towards a more maternal or professorial role. Bill would be kind of weirded out by the fact that the Doctor has a wife at first, but once she got over that, she would think River was super awesome, and River would be absolutely impressed by Bill’s humor and wit.

Toshiko Sato (Bisexual maybe? It mighta been because of aliens) (has a sexual and romantic relationship with a woman but also has romance with a man)

The Doctor (pansexual as theorized by fandom) (kissed Rory as well as pretty much everyone else.) (Other theories on The Doctor’s sexuality include asexuality, heterosexuality, bisexuality, omnisexuality, polyamorous, and pretty much anything else you can think of.)

River Song (Bisexual or maybe pan. Moffat has referred to her as bi and I believe Alex has as well, but I’m not sure if the identity is confirmed since Moffat called Jack bi in the same tweet which is not accurate) (Married to at least 2 women and 3 men and flirts with anything that moves.) (Also might be considered polyamorous)

Madame Kovarian (Lesbian?) (Moffat has claimed she used to be married to Tasha Lem)

• Captain Jack Harkness. I may not talk about him much, but he’s awesome.

• The epic adventure music we had in Matt Smith’s era. That was my jam back in the day.

• The casual LGBT representation. It’s been there since series one, but it’s never been a big deal.

• The Drunk Giraffe.

• There was actually an episode that used as many oo sounds as possible (Judoon platoon upon the Moon!) just to mess with David Tennant, because it was hard for him to maintain his English accent and say those words.

• I love the Master and Missy in equal amounts, because they are evil because they can be, and still act like the Doctor’s their best friend, especially Missy.

• Honestly, I’ll be sad to see Missy go- she’s basically a big ball of Glaswegian craziness, and she’s brilliant as a villain.

• The Paternoster Gang, because only on Doctor Who would you have a team comprised of a pair of interspecies crime solving lesbians and their pet potato.

• Nardole, mother hen extraordinaire.

• Amy and Rory’s relationship.

• “It’s smaller on the outside!”

• “Allons-y, Allonso!”

• “Bow ties/ Fezzes/ Stetsons are cool.”

• The Doctor’s entire message in Blink.

• All the nods to the Doctor’s past- Sarah Jane, UNIT, the Master, all the old monsters, even things like Twelve offering someone a jelly baby and the return to Coal Hill School.

the worst feeling is when you are watching a tv show you got spoiled a few times and a character that you know dies appears and you’re like “this is it. this is how I’m gonna love them and get my heart ripped off”
